Mirrors ?

The only morrors I would consider are Halcyon made in stainless with an expander that works and wont fall to bits , replacement glass on line ,and semi concealed adjusters to stiffen the action .  Worth the money but not cheap compared to Chinese crap.

I have Halcyon bar end mirrors on 3 bikes now, and as Robert says they just work. I think mine are the 830 type.
Remember the old phrase "the quality is remembered long after the price is forgotten".
Image clarity is OK up to around 80-85mph on the Norton, then the vibes start interfering.

I've got an Oxford bar end mirror, stands up to the vibrations of a 500 single! But watch out not all bar thicknesses are the same.

hello,

on my 500 single.

after trying one or two cheap mirrors, none would stay put. some would fly off in the wind no matter how tight they were. at certain rev you slowly got a view of the tarmac when they vibrated loose. on fitting some raised handle bars i wondered if i could fit an old set of mirrors i had. they were off a triumph adventurer 900. its the sort of mirror you can grab hold of to push the bike around with they are fairly sturdy. dont know what view you would get on straight bars. i think its worth as already mentioned buy some dearer types, better quality ones.

If it's a Dommie, you ought not to have problems with bar internal diameter. My 1937 machine was a problem.  I had to mount the bar fitting onto a mandrel and turn it down on the lathe to fit.  Bar wall thicknesses were a lot less later on.

Only old English bike I have where rear view isn't blurry is a Vincent with bar end mirror. All with long distance between mirror and handlebar gives blurry vision.

I use stadium or halcyon bar end mirrors on my dommi.  Avoid the cheaper mirrors they do not give a very wide view giving potential blind spots. I suffered from vibration on my mirrors which became a blur after 30mph.  Filling the bars with molten lead reduced the shake. Also I discarded the steel expander within the bars and replaced it with suitable sized rubber pipe. I now have good vision up to 50mph.

They flip in.  I sometimes do it in heavy traffic.

Yes measure the inside diameter and check they'll fit yours, i tried making a sleeve but it didn't work well, they kept slipping.

hello ,   makes you wonder if a small adjustable weighted clamp on the stem would make a difference. so that you could move it up or down the mirror stem, to change the mirrors resonant frequency at a certain rev.
i know, i banged my head this morning.  barry.

On my first ride my eyeballs wobbled so much at 50mph that I couldn't see where I was going.  Head steady bolts were loose.  Huge improvement after they were tightened.
Your 99 ought not to vibrate uncomfortably.

Unless there is something very wrong, it sounds like loose head steady.  A loose steady causes such severe vibration that it can apparently damage the frame.  It's not accessible without removing the tank.

Just bolted solid.  No rubber involved.

Do you have the standard stay?  It has a twist at the lower (head) end, where it flattens out to sit onto the head. If it's at an angle, surely there must be a triangulat gap?  That won't do it or the stud any good.  All the load should be carried by friction between the surfaces of the stay and the head - the stud makes sure they are tightly held together.  A picture would help.

....I fit one of these mirrors to my '48 Inter and couldn't have been more pleased.  Expensive but very well made, unobtrusive, and nicely adjustable.

I bet the owner wore a knee length Parker with a hood and covered in graffiti, with the scooter hiding a rattle can air horn behind the right leg shield!!
I wondered what happened to Barry Vasey from all of those years ago.

Do people recommend the round bar-end mirror or the oblong one?
